“…In condition of numerical simulation, the damage pile stress wave accords with practical application. 300 groups of pile torsion wave signal data including 5 damage types are obtained by finite difference numerical simulation method [16], where fifteen percent of the data are forecast samples. The proposed method is applied to feature extraction, and the BP Neural Networks predicts classification [17].…”

The torsional low strain integrity test (TLSIT) is now regarded as the most potent alternative to the longitudinal wave test for the existing pile evaluation. However, the lack of the 3D wave theory for the TLSITs greatly hinders the application of this method. This paper establishes a coupled 3D soil-pile model based on the continuum theory. A corresponding analytical solution of the dynamic pile response is derived and subsequently verified through the comparisons against the 1D wave theory and the Finite Difference Method. The proposed model exhibits the transverse wave interferences and finds: (1) The transverse wave interference that occurred during the TLSITs can be seen gradually alleviated from the pile center to the pile edge. (2) The larger the pile dimensions are, the greater the transverse wave interference would be.
